Benign carcinoid tumors of other sites

This code identifies a non-cancerous neuroendocrine tumor originating from enterochromaffin cells, specifically located in sites other than the appendix, small intestine, large intestine, or stomach. These tumors are characterized by slow growth and the potential to secrete hormones, though they are generally considered benign.

Apply this code when documentation specifies a benign carcinoid tumor found in an "other" or unspecified site, such as the bronchus, lung, thymus, or ovary. This code is appropriate when the pathology report confirms a benign carcinoid and the primary site is not one of the more commonly specified gastrointestinal locations.

• Ensure the pathology report explicitly states "benign carcinoid" and identifies a site not covered by more specific D3A.0 codes.
• Do not use this code for malignant carcinoid tumors; refer to the C7A.0 series for malignant neuroendocrine tumors.
• If the site is unknown or unspecified, consider querying the provider for clarification to ensure the most specific code is assigned.
